“…The rival vision of the relation between tenure security and housing improvement thus questions the necessity of legal title as a bearer of security for informal settlement dwellers and argues that tenure security is not, or at least not only, determined by legal category. The idea is that informal settlements simply improve over time as people invest in their housing even in the absence of rights as long as they think that they will not be removed by the authorities (Karst, 1971; Turner, 1976; Varley, 1987; Razzaz, 1993; Gilbert, 1994; 2002; de Souza, 2000; Payne, 2001; Ferguson and Navarrete, 2003; Aristizabal and Ortíz Gómez, 2004; Calderón, 2004; Broegaard, 2005). Factors that can contribute to perceptions of tenure security are signs of goodwill by government officials, the provision of services and infrastructure, length of occupation, size of the settlement and the degree of community organization (Payne, 1997; Durand‐Lasserve and Royston, 2002; Gilbert, 2002; Durand‐Lasserve, 2006).…”
